I suspect you need a new PCM. https://www.obd-codes.com/p0601
the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed
Can i just get a pcm and have it programmed ? Do i need to hsve key and skim module reprogramed as well?
